UNITED STATES PATENT LOUIS ROSSELL VVHITING, OF FORT WORTH, ASSIGNOR OFONE-FOURTH TO ALFRED MUOKLE, OF BOBBIN, TEXAS.

MACHINE FOR SHUCK lNG AND SHELLING CORN.

SPECIFICATION forming part of Letters Patent No. 382,285, dated May 1,1888.

To all whom it may concern:

Be it known that 1, LOUIS RossELL WHIT- ING, a citizen of the UnitedStates. residing at Fort Worth, in the county of Tar-rant and State ofTexas, have invented a new and useful Improvement in, Machines forShucking and Shelling Corn, of which the following isa specification.

My invention relates to an improvement in machines for shucking andshelling corn; and

it consists in the peculiar construction and combination of devices,that will be more fully set forth hereinafter, and particularly pointedout in the claims.

In the drawings, Figure 1 is an end elevation of my invention. Fig. 2 isa vertical sectional view of the same. Fig. 3 is a vertical section onthe plane at right angles to Fig. 2. Fig. 4 is a detailed elevation ofthe rib-frame. Fig. 5 is a detail perspective View of one of the ribs.Fig. 6 is a similar view of the cylinder-teeth.

A represents a rectangular vertical inclosing-case, which is provided onits upper side with an inletopening, B. On one side of the said openingis aninclined feed-board, G. On one side of the case A is adischarge-opening, D, in the lower side of which is located an in clineddelivery-board, E. The bottom of the case is formed by inclined boards Fand G, whichconverge downwardly, and between the lower edges of the saidboards is a dischargeopening, H. I represents a cylindrical case, whichis located below the board G, and in the said case is j on rnaled arotary fan orblower, K.

Horizontally and in the center of the case is journaled a shaft, L,carrying a cylinder, M, which is provided on its periphery withlongitudinal rows of teeth n. The said teeth are made by serrating theupper edges of angleplates N, as shown in Fig. 6, and then bolting thesaid angle-plates to the face of the cylinder, and arranging themparallel with each other. On one end of the shaft L, which projects beyond the case A, is secured a band-pulley, O, and a crank-handle, P, andon one end of the shaft of the fan K, on the same side of the case withthe pulley O, is secured a small pulley, R,which is connected to thepulley O by means of an endless belt, S.

T represents a concave frame, of which T are the end walls,which arelocated in the case A and secured on the shaft L near the ends thereof.Each end wall has its outer edge provided with serrations T having thelong tangential sides t, and the shorter sides, t", arranged at anobtuse angle with relation to the sides 25. On the opposing sides of theend walls are flanges t, which project inwardly from the sides t of theserrations, and on the said flanges are bolted ribs U, which connect theend walls together. have a long side, a, and a short side, a, the saidsides being arranged nearly at right angles to each other. The width ofthe long The saidribs U each sides a of the ribs is somewhat less thanthe flanges t, and when the said ribs are bolted on the said flanges topenings a are left between the edges of the ribs, which openings extendlongitudinally across the rib-frame and are parallel with each other.The ribs U project inwardly from the outer rims of the concave or ribframe toward the cylinder M, thereby forming abrading-shoulders a. Theend walls, T, of the rib or concave frame are provided on their lowersides and on the sides opposite the discharge-opening D of the case Awith pivoted or hinged sections T SpringsVbear against the free upperedges of the said hinged or pivoted sections and press the same towardthe-cylinder. The tension of the said springs may be regulated by theset-screws V, which extend through a flange, e, which depends from theinclined delivery-board E. On the outer end of the shaft L is secured alarge flywheel, W.

The operation of my invention is as follows: When the shaft L is rotatedin the direction indicated by the arrow in Fig. 2, the cylinder iscaused to rotate in the rib or concave frame, and the fan K is alsocaused to rotate in its case I, thereby creating a blast of air, whichstrikes against the inner side of the board F,

and proceeds upwardly along the said board,

and through the opening below the inclined delivery-board E, asindicated by the unfeathered arrows in Fig. 2. The corn to be shuckedand shelled is fed through the opening l3, and the ears are grasped bythe teeth of the rotating cylinder and forced between the face and thenrubs the grains from the cobs.

boards G and F, and are thereby conveyed to.

the opening H, where they are met by the blast of air from the fan orblower and thoroughly winnowed. The particles of dust and dirt and otherimpurities are discharged by the blast through the opening below theboard E, and the shucks and the cobs are discharged through the openingD above the said board. By providing the concave or rib frame with thehinged lower dischargesection and providing the springs bearing againstthe same it will be readily understood that the cobs and shucks areprevented from clogging the space between the cylinder and the concave,as the hinged portion of the latter is free to move outwardly underpressure of cobs of unusual size or compact bunches of shucks, so as topermit ready escape of the same.

Having thus described my invention. 1 claim- 1. The concave comprisingthe end walls, T, having their outer edges provided with the serrationsTflwhich have the long tangential sides t, and the shorter sides, t",arranged at an obtuse angle with relation to the sides t, and theflanges t on the opposing sides of the end walls and projecting inwardlyfrom the sides t of the serrations, and the ribs U, secured on the saidflanges to connect the end walls together, the

said ribs being narrower than the said flanges to leave openings atbetween the edges of the ribs, for the purpose set forth, substantiallyas described.

2. A corn shucking and shelling machine,

comprising the cylinder and concave, the inopening H between their loweredges, and the v blower to direct a current of air through the opening Hup the board F, and out of the-opening D below the board E, for thepurpose set forth, substantially as described.

In testimony that I claim the foregoing as my own I have hereto aftixedmy signature in presence of two witnesses.
